Build a playable Space Invaders-style game on a canvas using procedural graphics. Use HTML, CSS, and JavaScript as needed. Write it to `index.html` in the current working directory using your file tools. Inline your own CSS and JavaScript. Do not use external assets, CDNs, or network requests. No third-party libraries are provided. Required behavior: - Use Left/Right or A/D to move a cannon along the bottom and Space to fire upward. Display the controls and keep the cannon within the playfield. - Start with a grid of aliens that moves horizontally, reverses and descends at the edges, and fires toward the player. Player shots remove hit aliens and increase score once. - Place destructible bunkers between the cannon and aliens. Hits from either side remove bunker material persistently; shots can subsequently pass through the resulting gaps. - Start with three lives. Enemy shots cost a life with brief protection from repeated damage. Aliens reaching the player zone or zero lives causes Game Over; clearing the aliens shows a win state. - Provide Restart to restore aliens, bunkers, score, lives, and player position. Bound projectile lifetime and fire rate. Verify: Test movement and firing during the opening formation. Check alien motion and inspect a shot hitting a bunker or alien for visible damage or score feedback. Use Restart and check the initial formation, bunkers, lives, and score.

The game is now running and displays the following: 1. **Initial State**: - The game starts with a grid of aliens (red and yellow) at the top. - The player's cannon is positioned at the bottom center. - Two rows of bunkers are placed between the aliens and the cannon. - The score is `0` and lives are `3`. 2. **Controls**: - Left/Right or A/D keys move the cannon horizontally. - Spacebar fires a shot upward. 3. **Behavior Verification**: - **Movement**: The cannon moves smoothly with the Left/Right or A/D keys. - **Firing**: Pressing Space fires a bullet upward. - **Alien Motion**: Aliens move horizontally and descend when they reach the edge. - **Bunkers**: Bunkers are visible and appear destructible. - **Restart**: The Restart button resets the game to its initial state. ### Next Steps for Verification: - **Alien Shooting**: I will simulate firing a shot at an alien to check if it is removed and the score increases. - **Bunker Destruction**: I will simulate firing a shot at a bunker to check if it is damaged and if subsequent shots pass through the gaps. - **Game Over/Win**: I will simulate losing all lives or clearing all aliens to verify the game over and win states. Let me proceed with these checks.

The bullet was fired, but it did not hit any aliens or bunkers. Let me move the cannon to align with an alien and fire again to ensure a hit.

The cannon has moved to the right. Now I will fire again to test if the bullet hits an alien and increases the score.

The bullet hit an alien, but the score did not update (it remains at `0`). This indicates a collision detection issue where the alien is removed but the score is not incremented. Let me check the collision logic and fix it. I'll also test firing at a bunker to ensure it is damaged and shots pass through the gaps afterward.

The issue is that the score is already being updated correctly in the `checkBulletAlienCollisions` function. The problem might be that the bullet is not actually hitting the alien due to positioning or timing. Let me verify the collision logic and ensure the bullet is correctly aligned with the alien. I'll now test firing at a bunker to ensure it is damaged and shots pass through afterward.

The bullet did not hit the bunker either. It seems the issue is with the alignment or collision detection logic. Let me adjust the bullet's position and ensure it aligns correctly with the bunkers and aliens. I'll modify the bullet firing logic to ensure it aligns properly with the player's position.
